RULING DEVICE.

SPECIFICATION forming part of Letters Patent No. 752,556, dated February 16, 1904. Application filed October 29, 11903 Serial No. 179,094. (No model.)

To all whom it may concern:

Be it known that I, J OSEF HREN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Ruling Devices, of which the following is a specification.

By means of this invention adjustment can readily be made for ruling such number or arrangement of lines as may be called for.

This invention resides in novel features of constructions as set forth in the following specification and claim, and illustrated in the annexed drawings, in which Figure 1 shows a front elevation of the ruling device. Fig. 2 is a sectional front elevation of Fig. 1. Fig. 3 is a section along w m, Fig. 2. Fig. i is a section alongy Fig. 2. Fig. 5 shows a modification. Fig. 6 is a section along a a, Fig. 5.

The ruling-roller consists of a series of rails or tracks on which are mounted a number of diskiform rulers adapted to be set in any. desired position along the said rails, and the rails being engaged by a series of expanders the dislkiform rulers can be rigidly clamped to the rai s.

The bearing-roller is provided with anumber of coiled-wire springs which can be set on the roller to register with the diskiform rulers. i

In the drawings is illustrated a ruling-roller a and a bearing-roller b. The ruling-roller a is of skeleton form and is provided with journals c 0, having cylinder-heads d d. These cylinder-heads are provided with a number of slots 6, in each of which is guided an expander f and a rail or track 9. An end of each of the expanders f is screw-threaded and engaged by a nut h, which is prevented from moving longitudinally by a disk 11. On the rails g are mounted a series of rings or diskiform rulers j, and these rings can be slid longitudinally along the rails and placed in any desired position between the cylinder-heads (Z (2. Each expander f is tapered or wedge-shaped and engages with the tapered part of the track or rail 9 and when the nut h is turned it moves each of the expanders longitudinally to spread or contract the radius and diameter of each of the rails, thereby clamping or loosening the diskiform rulers. The bearing-roller b is provided with grooves in, which serve as rests for a number of coiled wire springs Z. The springs or elastic rings can be set any desired position apart on the bearing-roller, so that the springs and the ruling-flange of the diskiform rulers will register. A spring or ring Z at each side of a ruling-flange or ruler has been found to give a support for ruling or drawing a clean or sharp line. The rings and coiled springs can be set to any desired spacing or relation, and the rings and springs not to be used can be slid or set to one side or out of the way. When spaced or adjusted and clamped by the action of the expanders on the rails, the rings are held in position.

The number of rails and expanders is of course not limited to four or any specific numher; but the device shown has been found to work satisfactorily.

The device can be modified. The expander instead of being wedge-shaped or tapered can be provided with seats for balls on, Fig. 5, and such ball-carrying expanders f can be set longitudinally or screw-adjusted, as already stated. The railshaving concave or inclined seats or faces at the balls m and the latter acting against or moving toward a shallow part of these seats as the expander is being adjusted the rails will clamp the rulerrings, as before. The setting back and forth of the expander will thus spread the rails or allow them to come together or move toward the center or axis of the roller to clamp or unclamp the rulers.

I The device is not confined to the precise structure shown, as modifications can be made which are included in the invention. 'The expanding or expansiblerail can be rapidly set or loosened by the longitudinally-movable expanders.

What I claim as new, and desire tosecure by Letters Patent, is

1. A ruling device comprising ruling rings or disks, rails for the disks and expanders for the rails movable relative to said rails.

2. A ruling device comprising ruling rings or disks, expansible rails and longitudinallyinovable expanders.

3. A ruling device comprising ruling rings or disks, rails for the disks and longitudinallymovable expanders with set-screw for expanding and clamping the rails to the rings.

4. A ruling device comprising a cylinder having heads, rails made to move radially but not longitudinally in the heads, expanders made to move longitudinally in or through the heads, and a screw or adjusting nut mounted to rotate in a fixed plane and made to engage or adjust the expanders.

5. A ruling device comprising a rulingroller having rings, expansible rails for clamping or fixing the rings, expanders for the rails and a grooved bearing-roller having spring or elastic rings Which can be set along the roller into grooves.

6. A ruling device comprising adjustable rings or rulers With a bearing-roller having elastic or spring rings adapted to be set in conformity to the rulers.

' 7 A ruling device comprising rings or rulers, rails for the rulers provided with inclines, and expanders made, to set against the incline of the rail, the latter being movable longitudinally and independently of the rings and expanders.

8. A ruling device comprising ruling-rings, supports for said rings radially adjustable relative thereto, and means for adjusting said supports to said rings for clamping the same.

9. A ruling device comprising adjustable ruling-rings, supports radially adjustable relative to said rings, longitudinally movable members for adjusting said supports, and means for moving said members relative to said supports for clamping and unclamping said rings.

In testimony WhereofI have hereunto set my hand in the presence of two subscribing Witnesses.
